Yes, please!
How many times have I seen impoverished pensioners, many of them frail and/or disabled, giving their last two cents to such individuals?
And all because these villainous, pompous fakers preach a gospel of health, wealth and happiness, if only you will follow Jesus!
Nevertheless, Paul had some great wit, when it came to such 'grand delusions', as stated in Philippians 1:17:
17 The former preach Christ out of selfish ambition, not sincerely, supposing that they can stir up trouble for me while I am in chains.
18 But what does it matter? The important thing is that in every way, whether from false motives or true, Christ is preached. And because of this I rejoice.
Paul's way of seeing this type of showmanship: Let the donkeys bray! Because, in the end, these asses are promoting Jesus - whether they like it, or not!
Also, if you're smart, you'll chew on the meaty goespel, savouring every bite - while spitting out the bones and offal of falsehood! Just be sure to have a good-sized bucket handy, for the latter!
You'll need it!
